Based on your advice, our approach will be to generate a stable UUID on first encounter and store it in the object’s attribute dictionary, then read it back on all subsequent extractions. Does that sound like the right approach to you?

No. Use the persistent_id property.

But keep in mind that some geometric operation are destructive and destroy and recreate entity objects which cause loss of attribute dictionaries and a new persistent id being assigned. The Boolean operations are some that do this.
